AMD has developed a new system-on-chip (SoC) for Sony’s PlayStation 5 Pro, as reported on blog.playstation.com, which brings a number of changes to the existing model. One focus is on the integration of 60 compute units (CUs) based on the RDNA 4 architecture. These represent an increase on the 36 CUs of the current PlayStation 5 model. In addition to the additional compute units, there are also changes to the memory architecture and improvements to AI-based technologies.
The new PlayStation 5 Pro will continue to be based on AMD’s Zen 2 CPU architecture, but clock speeds will be slightly increased to ensure better performance. The GDDR6 memory will be 28% faster than that in the standard version of the PS5, resulting in a total bandwidth of 576 GB/s. In the area of graphics calculation, the ray tracing functionality has been further expanded. This enables more efficient calculation of reflections and light refraction, which should lead to better visual quality in games. This enhancement is based on changes in the RDNA 4 IP, which have been specially optimized for the PlayStation 5 Pro.
Sony is also introducing a new AI upscaling technology called PlayStation Spectral Super Resolution (PSSR). This technology uses machine learning to improve picture sharpness. PSSR is designed to increase the image quality of low-resolution games through AI-based optimization. Overall, the new PlayStation 5 Pro SoC is based on a reduction in the manufacturing process from 7 nm to 4 nm. This makes it possible to fit more transistors on the chip, resulting in better energy efficiency. Other features, such as the audio technology and memory architecture, remain largely unchanged, although there are some minor adjustments in terms of clock speeds and bandwidth.
The console is expected to launch on November 7. Pre-orders will be available from September 26.

This overview shows the most important technical changes of the PlayStation 5 Pro compared to the standard PS5 and Xbox Series X. The biggest differences to the PlayStation 5 concern the GPU, memory and the introduction of AI-driven upscaling technology based on the new SoC functions. The CPU remains largely the same for all models, but there are differences in the clock rate.
Further details on the availability and pricing of the new PlayStation 5 Pro were not fully disclosed at the time of the announcement.
